TRUCK SIDE FRAME.

SPECIFICATION forming part of Letters Patent No. 714,076, dated November 18, 1902. Application led May 5. 1902. Serial No. 106,089. (No model.)

T MZ w/om/ it 771,501/ concern:

Beit known that I, CHARLES T. WESTLAKE, of the city of Granite, Madison county, State of Illinois, have invented certain new and useful Improvements in Truck Side Frames,

of which the'following is a full, clear, and exact description, reference being had to the accom panying drawings, forming a part hereof.

My object is to construct an improved truck 1o side frame; and myinvention consists of the novel features herein shown, described, and claimed.

Figure 1 is an inside elevation of my improved truck side frame, the bolster and axles t5 being shown in section. Fig. 2 is a horizontal section taken on the line2 2 of Fig. 1 and looking downwardly. Fig. 3 is a cross-section on the line 3 3 of Fig. 1.

Referring to the drawings in detail, the 2o web 4 is at the extreme outer side of the side frame and has a bolster-recess 5 at its center and has journal-box recesses 6 in its ends. Flanges 7 extend inwardly from the web at the sides ot' the recess 5 and form the truckcolumns. A ange 8 extends inwardly from the web at the bottom of the recess and forms a rigid connection between the lower ends of the truck-columns. A bolt 9 is removably inserted through the truck-columns near their 3o upper ends, said bolt being located at the transverse center, as shown in Figs. 2 and 3. The links 10 are pivotally mounted upon the bolt 9 and located against the inner faces of the truck-columns, and a second bolt 11 con nects the lower ends of the links. The bolster 12 has a recess 13 in its lower face to receive the second bolt 11, as required, to-support the bolster and allow it to swing endwise between the truck-columns. The stops 14 4o project outwardly from the sides of the bolster in position to engage the truck-columns 7 and limit the swinging of the bolster. A tiange 1,5 extends inwardly from the web 4 and connects the upper ends of the truckcolumns. Y Flanges 16 extend inwardly from the web at the outer sides of the journal-box recesses 6 and form the outer journal-box housing-plates. Similar flanges 17 project inwardly from the web at the inner sides of the journal-box recesses ('5 and form the inner journal-box housing-plates. Flanges 18 project inwardly from the end and connect the upper ends of the truck-columns to the lower ends ot the outer housing-plates 16, and a ange 19 projects inwardly from the web and connects the lower ends ofthe inner housingplates ,17. Flanges 2O connect the upper ends of the outer housing-plates to the upper endsof the inner housing-plates and form spring-seats.

Journal-boxes 21 are slidingly mounted between the housing-plates 16 and v17, and the springs 22 are inserted between the springseats 2O and the journal-boxes 21. The trussbar 23 is secured in position to hold the journal-boxes in place, said truss-bar extending from one end of the side frame to the other. The braces 24 connect the truck-columns ot' one side frame to the truck-columns of the opposite side frame.

I claim- 1. Atruckside frame comprisingaweb having a bolster-recess at its center; flanges extending transversely from the web at the sides of the recess to form truck-columns; links pivotally mounted within said recess; and a bolster connected to the lower ends of the links as required to allow the bolster to swing endwise, substantially as specified.

2. Atrucksideframecomprisingawebhaving a bolster-recess at its center; flanges extending transversely from the web at the sides ot' the recess to form truck-columns; links pivotally mounted within said recess; a bolster connected to the lower ends of the links as required to allow the bolster to swing endwise; and stops to limit the swinging motion of the bolster, substantially as specitied.

3. Atrucksideframecomprisingawebhaving a bolster-recess at its center, said recess being primarily closed at the top; and means of swinging the bolster in said bolster-recess, substantially as specitied.

4. Atrucksideframecomprisingawebhaving a bolster-recess at its center and journalbox recesses in its ends; ianges extending inwardly from its end at the sides of the In testimony whereof I ax my signature in presence of two Witnesses.
